windows 2012 R2 系统下, redis 主从配置

环境

system: Windows 2012 R2

Redis: 5.0.10 64bit

原来只有一个节点进行读写，随着时间推移，时不时出现超时现象，于是改为1主（写）2从（读）方案。项目背景可以使 用 redis 只做缓存使用， 不需要持久化。

1，安装redis 后，再复制出两个文件夹。

端口： 

redis: 6379
redis_slave1: 6380
redis_slave2: 6381

2，分别打开 Redis_Slave1, Redis_Slave2 下的配置文件， redis.windows.conf, 在“Replication" 部位添加配置：

slaveof 127.0.0.1 6379

################################# REPLICATION #################################

# Master-Slave replication. Use slaveof to make a Redis instance a copy of
# another Redis server. A few things to understand ASAP about Redis replication.
#
# 1) Redis replication is asynchronous, but you can configure a master to
#    stop accepting writes if it appears to be not connected with at least
#    a given number of slaves.
# 2) Redis slaves are able to perform a partial resynchronization with the
#    master if the replication link is lost for a relatively small amount of
#    time. You may want to configure the replication backlog size (see the next
#    sections of this file) with a sensible value depending on your needs.
# 3) Replication is automatic and does not need user intervention. After a
#    network partition slaves automatically try to reconnect to masters
#    and resynchronize with them.
#
# slaveof <masterip> <masterport>
slaveof 127.0.0.1 6379

3，注册为windows service

分别到Redis_Slave1, Redis_Slave2 文件夹下执行命令。注意： redis-server.exe 前面有"." ， 如果不加"." 执行的是系统全局命令，将无法启动多个服务。

# 文件夹 Redis_Slave1
.
edis-server.exe --service-install redis.windows.conf --service-name Redis6380
# 文件夹 Redis_Slave2
.
edis-server.exe --service-install redis.windows.conf --service-name Redis6381

在win服务里查看执行结果：

4，验证安装

通过redis-cli 命令分别登录服务，并测试一个key,
